There is a easy way to get the multiplication with 11.
suppose if any one ask you 53*11
then what you will do?
You will multiply that is
53
53*
____
583
_____ This is the final result.
but this may take some time to calculate.
So we can use a trick to calculate this with in a second.
53*11= 5+3=8 so place this 8 between 5 and 3 that is 583 there for the answer is 583
This is known as MATHMAGIC
If the calculation with 3 digit number
then 583*11= 5+3=8
Now place this 8 in between 5 and 3
that is 5883
5(58 8+3)3
5(5(8+1)1)3
5(591)3
5(5+9)13
5(14)13
(5+1)413
6413
very simple. Just try it.
I hope you understood.
